effect of temperature during cement grinding

  • free limePage 1 of 2International Cement Review

    Apr 05 2011 · Normally free lime( calcium oxide) is present in clinker whereas in the cement a major portion of it is present as Calcium hydroxide. This is due to the fact that during the process of hydration it absorbs the water either from the gypsum( moisture content) or from the high temperature developed during the process of grinding.

    Fine grinding lessens this effect and early cements had to be stored for several months to give the calcium oxide time to hydrate before it was fit for sale. From 1885 onward the development of specialized steel led to the development of new forms of grinding equipment and from this point onward the typical fineness of cement began a steady

  • Industrial versus Laboratory Clinker Processing Using

    The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet the results obtained cannot be directly transposed to industrial mills given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closed-circuit tube mill operating at

    Dec 24 2019 · Generally a concrete temperature is limited to 70°C (160°F) during hydration. If the temperature of the concrete during hydration is too high it will cause the concrete to have high early strength development but consequently gain less strength in the later stage resulting in lower durability of the structure overall.
